5 May 2013 (1.2) Make Material Board

Arrange the materials collected, judging the pros and cons, then paste the selected material on the moating board, preparing for final selection.

Do research on Internet for the materials I collected,

Material Board 1

Acrylic

Properties: Stiff, hard, glass clear very durable Outdoors, Easily machined, cemented and Polished. Good electrical insulator. Safe with food 10X more impact resistant than glass.

Pros: Acrylic resin in its solid form makes a good alternative to glass.

Cons: Solid acrylics should not be used to support extremely heavy loads, as it becomes brittle under

weight.

Softwood

Properties: wood from gymnosperm trees such as conifers. Evergreen trees are often called softwoods with the notable exceptions being bald cypress and the larches.

Pros: water-proof, Cheaper, More environmentally friendly as it takes less time to grow, sustainable because you can plant another tree in the place of the one you chop down.

Cons: Weaker than hard wood, lasts less longer than hardwood as it is easily broken.

Nylon Rope

Properties: Nylon, chemically known as polyamide, is the most widely produced synthetic fibber in the world. According to Cambridge Encyclopaedia, nylon represents a group of synthetic polymers called thermoplastics.

Pros: Good Elasticity, Static Resistant, Good resiliency, Non-Absorbent.

Cons: Nylon is almost always acid dyed. It is rarely solution dyed, so it can have problems with bleaching, fading.

PVC

Properties: PVC, PE, PP and PS are general-purpose plastics. The features of the particular plastic aredetermined by its chemical composition and type of molecular structure (molecular formation: crystalline/amorphous structure)

Pros: more stronger, good electrical resistant, cheap

Cons: Don't heat

 Material Board 2

Glass

Properties: Specific glass properties of interest can be determined from the chemical glass

composition, for example given a commercial soda lime or borosilicate glass.

Pros: Superior accuracy, Time and financial savings, Compatibility.

Cons: Easy to broken.

Iron wells

Properties: Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms.

Pros: cheap, To randomly to their shape.

Cons: Iron rusts in dump air, but not in dry air.

Aluminium

Properties:  Aluminium is a very light metal with a specific weight of 2.7 g/cm³, about a third that of steel .

Pros: no rust, very strong, light weight, impact resistant can be molded and shaped with relative

ease (must be heated first) Aluminum is a very abundant resource

Cons: liquid aluminum can have cause serious health problems if damaged aluminum is difficult

to reshape or repair.

Material Board 3

Cobblestone

Properties: heat conduction, melting point，

Pros: Nature, Japan Style, breakage-proof

Cons: Get hot easily, Hard to cut

Cotton

Properties: Cotton is a natural fibber and it is harvested from the cotton plant. The properties of cotton are many– it is soft, versatile and strong – to mention a few.

Pros: Can change shape at will.

Cons: Easy get dirty, It is not easy to clean.

Leather

Properties: Leather fibres will hold large quantities of water vapour. This property enables leather to absorb perspiration, which is later dissipated.
A significant factor in comfort.

Pros: more stronger, good electrical resistant.

Cons: expensive
